Industrial fluids
Regular removal of solids, water, and tramp oil keeps your machines running. GEA separators ensure efficient bypass treatment for reliable, hygienic operation.

Coolant emulsions are essential in metalworking as they reduce friction and forming energy, dissipate heat and flush away metal shavings during machining and forming operations. To perform these tasks, emulsions are complex mixtures of emulsifiers, stabilizers, corrosion inhibitors, high-pressure additives and mineral oil components. However, this complexity makes them prone to bacterial contamination and rapid degradation, especially when impurities like metal shavings and tramp fluids are present.
If left untreated, coolant emulsions can break down, causing acid formation, discoloration and even skin irritation for operators. Fast, effective removal of solids and tramp oil is essential to maintain coolant quality and ensure safe, efficient operations.
GEA separators are engineered for seamless integration into your production process, enabling early, partial stream purification. Our technology simultaneously removes fine solids and tramp oil in a single cycle - extending coolant life by up to five times, minimizing machine downtime and improving hygiene as well as working conditions.
With GEA’s proven centrifugal technology and global service network, you can count on reliable, continuous purification of coolant emulsions - even in the most demanding industrial environments.

Since 2019, GEA has risen from underperformer to DAX member – one of Germany's top 40 listed companies – by fostering entrepreneurship and turning sustainability into a competitive advantage. It reached this milestone in its nearly 145-year history without tailwinds or shortcuts, in a world of compounding crises. This turnaround shows what's possible when purpose and performance align.
This year was a big one for GEA. Can you remember all the milestones and highlights?
The GEA Foundation launched this year with a promise: to make a tangible difference in people's lives. From scholarships in Germany to clean water in Tanzania, the foundation is already proving that when companies commit to giving back, lives change.
